Parallelization of the ADAPT 3D Streamer Propagation Code

In order to run Computational Fluid Dynamics (CFD) codes on large scale infrastructures, parallel computing has to be used because of the computational intensive nature of the problems. In this paper we investigate the 3D version of the ADAPT platform where we do a coupling between flow partial differential equations and a Poisson equation. This coupling leads to a linear system that we solve using direct methods. The implementation is conducted with the MUMPS parallel multi-frontal direct solver and with METIS for mesh partitioning methods to improve the overall performance of the framework. We also investigate, specifically in this paper, how the mesh partitioning methods are able to optimize the mesh cell distribution of the ADAPT solver.
